## react-native-video
A `<Video>` component for react-native, as seen in
[react-native-login](https://github.com/brentvatne/react-native-login)!
Requires react-native >= 0.19.0
### Add it to your project
Run `npm i -S react-native-video`
#### iOS
Install [rnpm](https://github.com/rnpm/rnpm) and run `rnpm link react-native-video`.
If you would like to allow other apps to play music over your video component, add:
**AppDelegate.m**
```objective-c
#import <AVFoundation/AVFoundation.h> // import
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:nil]; // allow
...
}
```
#### Android
Install [rnpm](https://github.com/rnpm/rnpm) and run `rnpm link react-native-video`
Or if you have trouble using [rnpm](https://github.com/rnpm/rnpm), make the following additions to the given files manually:
**android/settings.gradle**
```
include ':react-native-video'
project(':react-native-video').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-video/android')
```
**android/app/build.gradle**
```
dependencies {
...
compile project(':react-native-video')
}
```
**MainActivity.java**
On top, where imports are:
```java
import com.brentvatne.react.ReactVideoPackage;
```
Under `.addPackage(new MainReactPackage())`:
```java
.addPackage(new ReactVideoPackage())
```
### Note: In react-native >= 0.29.0 you have to edit `MainApplication.java`
**MainApplication.java** (react-native >= 0.29.0)
On top, where imports are:
```java
import com.brentvatne.react.ReactVideoPackage;
```
Under `.addPackage(new MainReactPackage())`:
```java
.addPackage(new ReactVideoPackage())
```
## Usage
```javascript
// Within your render function, assuming you have a file called
// "background.mp4" in your project. You can include multiple videos
// on a single screen if you like.
<Video
source={{uri: "background"}} // Can be a URL or a local file.
rate={1.0} // 0 is paused, 1 is normal.
volume={1.0} // 0 is muted, 1 is normal.
muted={false} // Mutes the audio entirely.
paused={false} // Pauses playback entirely.
resizeMode="cover" // Fill the whole screen at aspect ratio.
repeat={true} // Repeat forever.
playInBackground={false} // Audio continues to play when aentering background.
playWhenInactive={false} // [iOS] Video continues to play whcontrol or notification center are shown.
onLoadStart={this.loadStart} // Callback when video starts to load
onLoad={this.setDuration} // Callback when video loads
onProgress={this.setTime} // Callback every ~250ms with currentTime
onEnd={this.onEnd} // Callback when playback finishes
onError={this.videoError} // Callback when video cannot be loaded
style={styles.backgroundVideo}
/>
// Later on in your styles..
var styles = StyleSheet.create({
backgroundVideo: {
position: 'absolute',
top: 0,
left: 0,
bottom: 0,
right: 0,
},
});
```
### Load files with the RN Asset System
The asset system [introduced in RN `0.14`](http://www.reactnative.com/react-native-v0-14-0-released/) allowed loading image resources shared across iOS and Android. As of RN `0.31` [the same is true](https://github.com/facebook/react-native/commit/91ff6868a554c4930fd5fda6ba8044dbd56c8374) of mp4 video assets for Android. As of `0.32` iOS should also be supported. Requires `react-native-video@0.9.0`.
```
<Video
repeat
resizeMode='cover'
source={require('../assets/video/turntable-loop-1920x500-h264-512kbps-h264.mp4')}
style={styles.backgroundVideo}
/>
```
### Play in background on iOS
To enable audio to play in background on iOS the audio session needs to be set to `AVAudioSessionCategoryPlayback`. See [Apple documentation][3] for additional details.
## Static Methods
`seek(seconds)`
Seeks the video to the specified time (in seconds). Access using a ref to the component
## Examples
- See an [Example integration][1] in `react-native-login` *note that this example uses an older version of this library, before we used `export default` -- if you use `require` you will need to do `require('react-native-video').default` as per instructions above.*
- Try the included [VideoPlayer example][2] yourself:
```sh
git clone git@github.com:brentvatne/react-native-video.git
cd react-native-video/Examples/VideoPlayer
npm install
open VideoPlayer.xcodeproj
```
Then `Cmd+R` to start the React Packager, build and run the project in the simulator.
- [Lumpen Radio](https://github.com/jhabdas/lumpen-radio) contains another example integration using local files and full screen background video.
## TODOS
- [ ] Add support for captions
- [ ] Add support for playing multiple videos in a sequence (will interfere with current `repeat` implementation)
- [ ] Callback to get buffering progress for remote videos
- [ ] Bring API closer to HTML5 `<Video>` [reference](http://devdocs.io/html/element/video)
